Definitions
- This invention relates to a dispenser for fluid substances, in particular creams or liquids, of the type comprising a container defining an elongate chamber to contain the substance and closed at one end by a piston movable along the chamber.
- a fluid substance dispenser is known provided with a single chamber containing the substance, which is compressed by elastically deforming a portion of the dispenser, in order to deliver it through a discharge nozzle.

- the dispenser of the invention is advantageously constructed of any known rigid plastics material by moulding; only the non-return valve 8 and the cap 9 are constructed of rubber or of any known flexible plastics material.
- the dispenser is operated in the following manner. After removing the cover 25 a portion of the deformable cap 9 is pressed (see Figure 2); this increases the pressure within the compression chamber 10, to consequently separate a portion of the edge of the hole 14 in the cap 9 from the end 13A of the appendix, and create an aperture ( Figure 2) for the delivery of the substance; the substance contained within the chamber is unable to return to the container because of the presence of the valve 8, and hence flows outwards through said aperture.

- the substance which has left the compression chamber 10 cannot stagnate either within the hole 14 or on the free end 13A of the appendix 13.
- the mobility of the edge of the hole 14 relative to the end of the appendix 13 is better than in the case of the delivery and non-return valves of known dispensers in that in these latter the substance is present and remains present on both faces of these valves (both that facing the compression chamber and that facing outwards) present in the delivery nozzle.

Abstract
Description
- This invention relates to a dispenser for fluid substances, in particular creams or liquids, of the type comprising a container defining an elongate chamber to contain the substance and closed at one end by a piston movable along the chamber.
- A fluid substance dispenser is known provided with a single chamber containing the substance, which is compressed by elastically deforming a portion of the dispenser, in order to deliver it through a discharge nozzle. In these dispensers the piston movable within the chamber is provided with means which prevent it retracting when the substance is put under pressure.
- These means can consist of a toothed rod or the like extending through the entire container chamber from its head and passing through a hole provided in the piston.
- At the hole there are provided elements which engage the rod to enable the piston to move only towards the container head.
- Each time the dispenser is operated, the rod is lowered within the hole in the piston, which is then dragged by the rod towards the container head when the dispenser ceases operation to return elastically into its rest state (dispensers of this type are described for example in US-A-2732101, US-A-2356874 and US-A-4421255).
- In another type of dispenser with a single substance-containing chamber, radially projecting metal lugs are rigid with the piston and have their ends in contact with and pressing against the cylindrical wall of the containing chamber to enable the piston to move only in the direction towards the delivery nozzle. Whenever the dispenser is operated the piston is unable to retract during the compression of the substance, achieved by pressing a deformable part of the dispenser, because of the effect of the lugs.
- When said pressing ceases and the first deformed part returns elastically to its rest position, a vacuum is generated in the chamber to cause the piston to rise within the chamber (dispensers of this type are described for example in EP 0051790, EP 0084638, US 30888636 and US 3768705).
- These types of dispenser, comprising a single chamber acting simultaneously as the substance container and the compression chamber for the substance, have the drawback of being very costly (for example because of the provision of the toothed rod and the system for its engagement with the piston, and because of the provision of metal lugs rigid with the piston respectively), of being rather difficult to assemble, and requiring a rather large force for their operation.
- To overcome the aforesaid drawbacks dispensers are known having two separate chambers communicating via a non-return valve. Of the two chambers, one is cylindrical and is intended only to contain the substance, it being closed at one end by a sealed piston freely slidable within the chamber.
- The other chamber, which acts as the compression chamber, is at least partly deformable (to compress that part of its contained substance which has been drawn through the non-return valve by the vacuum in the collection chamber) and comprises a delivery nozzle provided with a shut-off valve to only allow the substance to pass to the outside.
- When delivery ceases, the deformable part returns to its rest position to close the nozzle, and the wall of the cap in returning to its rest position generates a vacuum which draws the substance from the cylindrical chamber to the compression chamber through a non-return valve.
- These types of dispenser (described for example in US-A-4402431, EP-A-0097972 and EP-A-0013691) are much simpler than those heretofore described, but have the drawback that the delivery nozzle comprises an elastically closable non-return valve (which opens when the substance is compressed and closes elastically when delivery ceases).
- This valve is inserted into a delivery nozzle in which a portion of relatively considerable length lies downstream of said valve.
- The result is that if the dispenser is not used for a fairly lengthy period, the substance tends to harden within said nozzle and/or in contact with the discharge valve, to obstruct them or make operation and delivery extremely difficult.
- In any event, the sealing of the non-return valve inserted into the nozzle is very problematic because this valve is in direct contact with the substance both upstream and downstream of the valve.
- An object of the invention is to provide a dispenser of this latter type which is of extremely simple structure, easy operation and reliable action, low production cost, free from delivery ducts in which the substance can stagnate, and in particular with no valve positioned within said ducts.
- This and further objects are attained by a fluid substance dispenser with a deformable head comprising a container defining an elongate chamber to contain the substance and closed at one end by a piston movable along, and provided with members sealing against, the inner cylindrical wall of the chamber, and closed at its other end by a transverse fixed wall comprising at least one passage at which there is provided a non-return valve arranged to allow the substance to emerge from the chamber, on the outside of said container and rigid therewith there being provided a deformable cap defining with said transverse fixed wall a compression chamber, there being provided a nozzle for discharging the substance from said compression chamber and a closure member for said nozzle, wherein from said transverse fixed wall there extends into said compression chamber at least one elongate appendix the free end of which is positioned at a hole provided in said deformable cap, the cap edge in correspondence with said hole being elastically urged to seal against said free end when the cap is in its rest state, that portion of the cap in correspondence with its hole plus the adjacent end portion of the appendix together forming said discharge nozzle and said nozzle closure member.
- For a better understanding of the invention one embodiment of the dispenser is shown by way of non-limiting example on the accompanying drawings, in which:
- Figure 1 is a section through a dispenser according to the invention in its rest state ready for use;
- Figure 2 is an enlarged sectional view of the head of the dispenser of Figure 1, shown during substance delivery; and
- Figure 3 is an enlarged view of a portion of the movable piston forming part of the dispenser.
- With reference to said figures, a substance dispenser according to the invention comprises a
container 2 defining an elongatecylindrical chamber 3 for containing the substance and closed at one end 3A by apiston 4 and at itsother end 3C by a transversefixed wall 6 comprising a plurality of passages 7 (only one is visible in the figures) at which there is provided a non-return valve 8. On the outside of the container and rigid with it there is provided adeformable cap 9 which together with the transversefixed wall 6 of the container defines acompression chamber 10. - From said transverse
fixed wall 6 there extends into thecompression chamber 10 anelongate appendix 13 thefree end 13A of which is positioned at asubstance delivery hole 14 provided in thecap 9. - Specifically, the
container 2 comprises at its end 3A acircular support base 18 and, internally, acircular rib 19 acting as a limit stop for thepiston 4. At itsupper end 3C the container comprises anannular slot 20 with an internalannular step 20A, to act as a seat for thecap 9, the lower edge of which rests in the slot and cooperates with thestep 20A so that the cap is securely connected to and sealed against the container. - The
annular slot 20 is defined by an end portion of thecontainer wall 2 and a wall 7A opposing and inwards of this latter, and also acting as a connection between thewall 6 and the side wall of the container. - At the passages 7 the
wall 6 comprises anannular step 6A extending towards thechamber 10 defined by thecap 9. - The non-return valve 8 consists of a substantially
tubular part 15A to be mounted about theappendix 13 and adiscoidal part 15 extending from the lower edge of the tubular part. - The
discoidal part 15 is flexible and its free edge is elastically pressed against theannular step 6A of thewall 6 so as to form a seal against said wall when the dispenser is in its rest state. - The
discoidal part 15 rises from said step to hence connect together thechambers chamber 10 from the chamber 3 (as explained hereinafter) after a certain quantity thereof has been dispensed. - The
elongate appendix 13 extends centrally within thewall 6 and coaxial to thecontainer 2. In the illustrated example the appendix is substantially cylindrical and comprises, connected to thewall 6, a lower part which is of greater diameter than the upper part. - The
free end 13A of theappendix 13 has a half-dome extending centrally from the flat circular base of the appendix so as to form at saidend 13A a sort of rounded step. - The
cap 9, of hollow cylindrical form, has a rounded free end and is provided centrally with ahole 14 coaxial with thecontainer 2 andappendix 13. Anannular projection 21 extends into thecompression chamber 10 from the edge of thehole 14. - When in the rest position (Figure 1) the
annular projection 21 and the edge of thehole 14 in the cap are elastically urged against theend 13A of theappendix 13 so as to form a seal and prevent the substance present in thechamber 10 from emerging through thehole 14. - The
piston 4 is provided withmembers 5 which seal against the innercylindrical wall 3B of thechamber 3 and can move along this wall. - The
seal members 5 consist of a circular wall concave towards theopposing wall 3B of the container. Thewall 5 is shaped such that the wall edges are elastically urged against thecontainer wall 3B to hence prevent the substance contained within thechamber 3 from escaping lowerly or prevent air entering thechamber 3. - Above the
sealing wall 5 the piston comprises afront wall 23 connected to thewall 5 by awall 22. Thewall 23 comprises acentral hole 4A bounded by aboss 24 extending towards the container end 3A and sealable by aplug 16 which originally (as described hereinafter) is connected to thefree edge 24A of the boss 24 (Figure 3) byteeth 17 breakable by pressure exerted on the plug. - Finally, the dispenser comprises a
cover 25 for thedeformable cap 9. - At its free edge the
cover 25 comprisesinternal projections 25A to retain the cover on thecap 9 when mounted on the cap. - On that
flat face 25B of the free end of thecover 25 which faces thecap 9 there is provided a centralannular projection 26 arranged to rest against the edge of thehole 14 in thecap 9 such that, when the cover is mounted on the cap, the edge of thehole 14 rests both against theend 13A of theappendix 13 and against said annular projection and is therefore unable to separate from the appendix for any reason, once the dispenser has been filled. - The dispenser of the invention is advantageously constructed of any known rigid plastics material by moulding; only the non-return valve 8 and the
cap 9 are constructed of rubber or of any known flexible plastics material. - Assuming that the
container 2 andcompression chamber 10 have both been previously filled with substance, ie that the dispenser is ready for use, the dispenser is operated in the following manner. After removing the cover 25 a portion of thedeformable cap 9 is pressed (see Figure 2); this increases the pressure within thecompression chamber 10, to consequently separate a portion of the edge of thehole 14 in thecap 9 from theend 13A of the appendix, and create an aperture (Figure 2) for the delivery of the substance; the substance contained within the chamber is unable to return to the container because of the presence of the valve 8, and hence flows outwards through said aperture. - When the
cap 9 is no longer pressed the deformed wall of the cap returns elastically into its rest position (Figure 1) and the edge of thehole 14 returns to sealedly adhere against the end of theappendix 13A. - Hence after a dispensing operation a vacuum is created in the
chamber 10 relative to thecontainer chamber 3, to draw substance into thechamber 10 from thechamber 3 and open the non-return valve 8. - In this manner the
compression chamber 10 is completely filled after each operation of the device and is hence immediately ready for further dispensing. - It should be noted that by virtue of the aforegoing the edge of the
hole 14 in the cap and thefree end 13A of theappendix 13 can be considered both as a delivery nozzle and as a closure member. The substance which has left thecompression chamber 10 cannot stagnate either within thehole 14 or on thefree end 13A of theappendix 13. In addition the mobility of the edge of thehole 14 relative to the end of theappendix 13 is better than in the case of the delivery and non-return valves of known dispensers in that in these latter the substance is present and remains present on both faces of these valves (both that facing the compression chamber and that facing outwards) present in the delivery nozzle. - The small number of components of the dispenser according to the invention facilitates and accelerates its assembly, which can be easily automated to lower production costs.
- The dispenser is filled in the following manner.
- The dispenser with the
cap 9 fitted on thecontainer 2 and thecover 25 mounted on the cap, but without thepiston 4, is inverted relative to its normal position of use (ie relative to Figure 1). A quantity of substance sufficient to fill the dispenser is poured into thechamber 3 via the end 3A of the container. In this initial filling stage the substance substantially does not penetrate into thecompression chamber 10. Thepiston 4 is then inserted, with a usual member (not shown but conventional) acting on the centre of the base of the piston to push it towards thecap 9 and compress the substance in thechamber 3, to also fill thechamber 10. - The piston is inserted very rapidly into the chamber 3 (the action on the piston is energetic) so that the air initially present in the
chamber 10 is compressed into the cap. - This latter, by the action of the hence compressed air, becomes inflated to create a passage between the edge of the
hole 14 and theend 13A of theappendix 13, so that the air can escape from thechamber 10 to the outside by passing through the spaces existing between thecover 25 and thecap 9. - In this manner the
chamber 10 can be filled, with substantially total elimination of the air contained in it. - The analogous problem of eliminating the air from the
chamber 3 when thepiston 4 is inserted is solved by virtue of thehole 4A provided in thebase wall 23. - When the substance filling the
chamber 3 offers excessive but predetermined resistance to the advancement of thepiston 4, theteeth 17 connecting theplug 16 to the boss 24 (Figure 3) are automatically broken, the teeth being dimensioned such as to withstand only a predetermined pressure force. The plug is hence urged (by the member acting on theplug 16 for mounting the piston in the chamber 3) into theboss 24, to close thehole 4A in the piston. - It should be noted that the
plug 16, being advantageously initially connected to the piston by thebreakable teeth 17, is automatically positioned in proximity to thehole 4A to be closed. - In a modification (not shown) to the described embodiment, flexible strips are provided extending from the
outer edge 6B (Figure 1) of thewall 6 and having rounded ends in contact with the inner wall of thecap 9, these strips being such as to facilitate the return of thecap 9 into its rest position after it has been pressed.
